摘要
山区公路修建过程中常见顺层岩石边坡,尤其是软岩顺层边坡或分布软弱夹层的顺层边坡,处理不当易引发坡体失稳变形。本文就平华公路一处典型的顺层岩石滑坡进行分析论证,根据坡体的地质结构特征与滑坡的变形机理提出三种治理方案,并从技术与经济两方面进行分析比选,最终推荐顺层刷坡与锚固工程结合的综合治理方案,快速有效根治了该处滑坡病害。
In the process of highway construction in mountainous area,bedding rock slope is often encountered,especially soft rock bedding slope or bedding rock slope with soft interlayer,and improper treatment easily leads to slope instability and deformation.This paper analyzes a typical bedding rock landslide in Pinghua highway,puts forward three treatment schemes according to the geological structure characteristics of the slope and the deformation mechanism of the landslide,compares the schemes from the technical and economic aspects,and finally recommends a comprehensive scheme combining bedding slope brushing and anchoring engineering,which can quickly and effectively cure the landslide disease.
